The Nuclear receptor subfamily 4 group A member 2 (Nr4a2) is crucial for the formation or maintenance of dopaminergic neurons in the central nervous system including the retina, where dopaminergic amacrine cells contribute to visual function. Little is known about which cells express Nr4a2 at which developmental stage. Furthermore, whether Nr4a2 functions in combination with other genes is poorly understood. Thus, we generated a novel transgenic to visualise Nr4a2 expression in vivo during zebrafish retinogenesis...

BACKGROUND: DNA topoisomerase IIβ (topo IIβ) plays a crucial role in neural differentiation and axonogenesis. Inhibition of topo IIβ activity in vitro and in vivo results in shorter axons and increased DNA damage. These molecular events also involve in Alzheimeramp#039;s disease (AD); however, the role of topo IIβ in the pathogenesis of AD remains to be elucidated. OBJECTIVES: We aimed to investigate the role of topo IIβ association with Nuclear receptor related 1 protein (Nurr1) in the onset of AD...

Prolonged inflammatory response contributes to the pathogenesis of chronic disease-related disturbances. Among nuclear receptors (NRs), the orphan NR4A subfamily, which includes Nur77 (NR4A1), Nurr1 (NR4A2) and NOR1 (NR4A3), has recently emerged as a therapeutic target for the treatment of inflammation. Areas covered: This review focuses on the capacity of NR4A receptors to counter-regulate the development of the inflammatory response, with a special focus on the molecular transrepression mechanisms. Expert opinion: Recent studies have highlighted the role of NR4A receptors as significant regulators of the inflammatory response...

Many genes are differentially expressed in the cortex of people with schizophrenia, implicating factors that control transcription more generally. Hormone nuclear receptors dimerize to coordinate context-dependent changes in gene expression. We hypothesized that members of two families of nuclear receptors (NR4As), and retinoid receptors (RARs and RXRs), are altered in the dorsal lateral prefrontal cortex (DLPFC) of people with schizophrenia. We used next generation sequencing and then qPCR analysis to test for changes in mRNA levels for transcripts encoding nuclear receptors: orphan nuclear receptors (3 in the NR4A, 3 in the RAR, 3 in the RXR families and KLF4) in total RNA extracted from the DLPFC from people with schizophrenia compared to controls (n = 74)...

The abnormality of nuclear receptor-related protein 1 (Nurr1) in expression and function can contribute to neurodegeneration of dopaminergic neurons and occurrence of Parkinson's disease (PD). However, its related mechanism in PD is still unknown. In this study, we found that Nurr1 was down-regulated and CCL2 was up-regulated in PD patients and PD mice. CCL2 promoted apoptosis and secretion of TNF-α and IL-1β in SH-SY5Y cells and inhibited cell viability while knockdown of CCL2 exerted the opposite effects...

Adverse early-life conditions induce persistent disturbances that give rise to negative emotional states. Therefore, early life stress confers increased vulnerability to substance use disorders, mainly during adolescence as the brain is still developing. In this study, we investigated the consequences of maternal separation, a model of maternal neglect, on the psychotropic effects of cocaine and the neuroplasticity of the dopaminergic system. Our results show that mice exposed to maternal separation displayed attenuated behavioural sensitization, while no changes were found in the rewarding effects of cocaine in the conditioned place preference paradigm and in the reinforcing effects of cocaine in the self-administration paradigm...

The present work was designed to study the mechanisms associated with Nurr1 modulation following early life permethrin (PERM) treatment during rat's life span. Here we demonstrate that PERM exposure in rats, at a dose close to No Observed Adverse Effect Level (NOAEL) for 15days during neonatal brain development leads to its accumulation long after exposure. In striatum from adolescent rats we detected an increase in DNA methyltransferases (DNMTs) such as DNMT1, DNMT3a, Tyrosine hydroxylase, monomeric and aggregated α-synuclein protein levels...

The nuclear receptor related-1 (Nurr1) protein plays an important role in both the development of neural precursor cells (NPCs) and cognitive functions. Despite its relevance, the effects of Nurr1 on adult hippocampal neurogenesis have not been thoroughly investigated. Here we used RT-PCR, western blot, and immunocytochemistry to show that adult hippocampal NPCs abundantly express Nurr1. We then examined the effect of Nurr1 activation on adult hippocampal NPCs using amodiaquine (AQ), an anti-malarial drug that was recently discovered to be a Nurr1 agonist...

Regulatory T (Treg) cells with high expression of both CD25 and Foxp3 are developed in the thymus and also peripheral tissues. Treg cells suppress the activation and functions of effector T cells raised against specific antigens and are crucial for maintaining immune homeostasis. Treg cell development is associated with the induction of and epigenetic alterations of forkhead transcription factor Foxp3. Foxp3 expression is increased by the activation of several transcription factors including nuclear factor-kappa B (NF-κB), nuclear factor of activated T cells (NFAT), and Smad3 in response to various signals such as TGFβ, retinoic acid, and rapamycin...

Parkinson's disease (PD) is one of the progressive neurodegenerative diseases of whose condition is characterized by dopaminergic neuronal cell loss and dysfunction in the substantia nigra pars compacta (SNpc) and the striatum. Recent studies have demonstrated that the nuclear receptor-related 1 protein (Nurr1) is critical of dopaminergic phenotype induction in mesencephalic dopaminergic neurons. Further, Nurr1 engages in synthesizing and storing dopamine through regulating levels of tyrosine hydroxylase (TH), dopamine transporter (DAT) and vesicular monoamine transporter 2 (VMAT2)...

BACKGROUND: Neural stem cells (NSCs) are pluripotent and self-renewing cells which could differentiate into diverse types of neural cells, such as dopaminergic (DA) neurons, the loss of which is the typical characteristic of Parkinson's disease (PD). This study aimed to examine the molecular mechanisms of BMP2-mediating NSCs differentiation into DA neurons. METHODS: Different concentrations of BMP2 were used to induce the differentiation of NSCs into DA neurons, which were characterized by the number and the neurite lengths of tyrosine hydroxylase (TH)+ and dopamine transporter (DAT)+ neurons by immunocytochemistry...

Disease genetics in admixed populations like Hispanic-Americans, African-Americans, etc. are gaining importance due to high disease burden in them. Furthermore, epidemiological studies conclusively prove ethnicity-based differential prevalence of Parkinson's disease (PD), since the American-Caucasians are more susceptible than Asian-Indians and Africans. Contradictorily, Anglo-Indians, an admixture of Europeans and Asian-Indians are five-times less susceptible than Indians. We evaluated the neural basis of this phenomenon using the cytomorphological features of susceptibility to nigrostriatal neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)...

Dopamine neurons are overstimulated by drugs of abuse and suffer molecular alterations that lead to addiction behavior. Nurr1 is a transcription factor crucial for dopamine neurons survival and dopamine production, activating the transcription of key genes like tyrosine hydroxylase (TH). Interestingly, nuclear factor-kappa B (NF-κB) has emerged as a new Nurr1 partner in response to inflammatory stimulus. In this study we evaluated the effects of single and repeated amphetamine administration in the expression of Nurr1 and the NF-κB p65 subunit in the rat ventral tegmental area (VTA)...

Liver fibrosis is a wound-healing response characterized with the accumulation of extracellular matrix (ECM). And hepatic stellate cells (HSCs) are the principal cell source of ECM. NR4A2 (Nurr1) is a member of orphan nuclear receptor NR4A family and acts as transcription factor. It participates in regulating cell differentiation, proliferation and apoptosis. We previously demonstrated that NR4A2 expression in fibrotic liver reduced significantly compared with normal liver and NR4A2 knockout in HSCs promoted ECM production...

: Intestinal ischemia/reperfusion (I/R) injury is a potentially life-threatening condition that can cause injuries to remote organs at the end stage. The damage caused by intestinal I/R insult induces changes in the barrier functions of the intestine, and the intrinsic mechanism of regeneration is often insufficient to restore barrier functions, as indicated by the high mortality rate of patients experiencing intestinal I/R injury. However, little is known about the mechanisms of intestinal regeneration after I/R injury...

Advances in neonatal care have allowed premature infants to survive at earlier gestational ages, but they are often afflicted with neurological delays or deficits. Maternal inflammation has been identified as a major risk factor for premature birth and once born, infants often require supplemental oxygen for survival. Nurr1 (NR4A2) is an orphan nuclear receptor with no known binding site and is essential for the growth of midbrain dopamine neurons. Others have reported that Nurr1 can act as an anti-inflammatory transcription factor in microglia and astrocytes and respond lipopolysaccharide (LPS)...

Parkinson's disease is characterized by the death of dopaminergic neurons in the substantia nigra. To understand the molecular mechanisms of the disease, an in vitro model is important. In the 1990s, we used the SV40 large T antigen to immortalize dopaminergic neurons derived from Embryonic Day 14 rat mesencephalon. We selected a clone for its high expression of dopaminergic neuron markers such as tyrosine hydroxylase (TH), and we named it 1RB3AN27 (N27). Because the original N27 cell line has been passaged many times, the line has become a mixture of cell types with highly variable expression of TH...

Parkinson's disease (PD) can degenerate dopaminergic (DA) neurons in midbrain, substantia-nigra pars compacta. Alleviation of its symptoms and protection of normal neurons against degeneration are the main aspects of researches to establish novel therapeutic strategies. PPARγ as a member of PPARs have shown neuroprotection in a number of neurodegenerative disorders such as Alzheimer's disease and PD. Nuclear receptor related 1 protein (Nurr1) is, respectively, member of NR4A family and has received great attentions as potential target for development, maintenance, and survival of DA neurons...
